FILTERS
Each facet is marked measured (we watched this happen), declared (the game says
so, and we did not check), derived (we grouped what the game told us).

Counts are exact, from the same query as the list below. A blank is a gap in our
measurement, never a "no": each facet spells its own. A measured zero is a
count; an unknown count is not a zero and never sorts as one.

In the left column, * is a value this listing is filtered to and - is one it is
filtered against. Both are choices in the query, not facts about a game.

  activity — measured  (?band=…)
    playersNow                317  connected now
  * activeThisWeek             70  active this week
    quiet                     482  quiet — no count above 0
    dark                        4  dark — not reached in a month

  last seen — measured  (?seen=…)
    day                        61  in the last 24 hours
    week                       68  in the last 7 days
    month                      70  in the last 30 days
    older                       0  longer ago
    never                       0  never reached

  WHAT WE COULD MEASURE
  Hiding these takes them out of your listing; it does not mean the game is
  empty.

  could not count — measured  (?uncounted=…)
    yes                         0  uncounted

  could not reach — measured  (?unreachable=…)
